<title>CCD focal-plane real-time image processor</title>

Abstract

A focal-plane-array chip designed for real-time, general-purpose, image preprocessing is reported. A 48 X 48 pixel detector array and a 24 X 24 processing element processor array are monolithically integrated on the chip. The analog, charge-coupled device-based VLSI chip operates in the charge domain and has sensing, storing, and computing capabilities. The chip was fabricated with a double-poly, double-metal process in a commercial CCD foundry. The simulation of an edge detection algorithm implemented by the chip is presented. An overview of the chip performance is described as well.
